Bug Description

When I press any of these keys, they sometimes stick. Shift stick approximately at every second press, Alt stick a couple of times a day. Sticking disappears when I press sticked key. At 8.10-10.10 everything was normal.

If sticked the left Shift button, then right Shift button cannot turn off sticking , and vice versa.
My keyboard is clean.

Also.
After update to from 10.10 to 11.04 after i press Ctrl+Shift (change language) Shift is HOLD (hardware work normal, no holds and brake). After single press to Shift its RELEASE.
I try delete ~/.kde and reinit KDE. Does not help.

Last test:
If i press CTRL+SHIFT - SHIFT is Hold
If i press SHIFT+CTRL - SHIFT is not Hold

Please FIX. Unreal for work!
